Bananas are one of the main foodstuffs in the city of Butembo. In order to understand the marketing circuit as well as the consumption of bananas at the household level, a study was carried out in the city of Butembo. Its objectives were to understand how the marketing system for cooking bananas and plantains is organized and structured, to identify the problems or difficulties that hinder the marketing of cooking bananas and plantains and to compare the consumption of plantains to that of cooking bananas in households. To achieve these objectives, a survey was conducted among 96 plantain and cooking banana sellers and 100 households were used for the consumption study. At the end of these surveys, the results reveal that the banana marketing circuit is characterized by a multitude of actors playing different functions and having divergent market logics. The majority of these players are retailers (69.07 %) and wholesalers in the consumer market (50.52 %). Processors and wholesalers at the place of production are less represented. The main constraints in the marketing of plantains and cooking bananas are related to losses due to the perishability of bananas, transport problems induced by the advanced state of disrepair of the roads in the supply areas, the lack of customers, the lack of banana conservation structure, price instability and lack of knowledge of the transformation of bananas into other products. This study shows that 100 % of surveyed households consume plantains (Ndizi) against 98 % of households that consume cooking bananas (Bisamunyu). Regarding the consumption of bananas within a household, the study shows that a household with an average household size can consume between 1 and 10 kg of cooking bananas per day and per meal with an average of 3.15±1.78 kg. The interpretation of the third quartile indicates that 75 % of the households surveyed consume a daily quantity of cooking bananas of less than 4 kg per meal. Regarding the consumption of plantains, in a household with an average household size, the daily quantity varies from 1 to 8 kg with an average of 2.39 ± 1.23 kg per meal. Indeed, 75% of surveyed households consume less than 3 kg of plantains per day and per meal.
